What is the term for vertical movement in surface water caused by wind?

Explanation:
Wind-driven forces create a three‑dimensional movement pattern in the surface ocean. The wind transfers momentum to surface waters, and due to the Coriolis effect, the resulting horizontal flow at depth (Ekman transport) sets up a vertical circulation pattern. This whole process is best described as wind-induced vertical circulation because it captures the mechanism behind both upward and downward movements of water caused by wind, depending on how surface waters diverge or converge. Upwelling is the upward movement itself, and downwelling is the downward movement, but the term wind-induced vertical circulation refers to the complete wind-driven vertical motion that drives those other processes.
